Trying to choose a tool to track the SERPs of your chosen keywords can be difficult. There has been a few issues lately with finding a tools which is accurate, reliable and updated regularly. Here are a couple of tools that we use:
Raven Tools
Raven tools is basically really really good. It is the most accurate I have come across so far and has a brilliant interface. On your profile dashboard you can have quick snippets of Google Analytics data and keyword rankings meaning you have a quick look to get an overview of how your site is doing. As well as SEO data, you can track Links and Social metrics.
SEOmoz
Another really good tool. You can set up multiple campaigns to track a few sites and all their data, from SERPs to Twitter followers. Probably my favourite thing about SEOmoz is that they have a lot of tools available so you can track every aspect of a campaign, and these tools are of brilliant quality. I also recommend FollowerWonk for anyone wanting to track social metrics, quality and influence of followers etc…
